- Ho cheka ka morao ke eng?
Ho phunya ka morao ke mofuta o khethehileng oa ho phunya lesoba le tebileng. Ha ho etsoa mapolanka a marang-rang a mangata, a kang mapolanka a 12-layer, re hloka ho hokahanya lera la pele ho la borobong. Hangata, re phunya lesoba (ho phunya le le leng) ebe re teba koporo. Ka tsela ena, mokatong oa pele o amana ka ho toba le mokatong oa 12. Ha e le hantle, re hloka feela mokatong oa pele ho hokahanya le mokatong oa 9, le mokatong oa 10 ho ea mokatong oa 12 hobane ha ho na khokahanyo ea mohala, joalo ka tšiea. Pilara ena e ama tsela ea pontšo 'me e ka baka mathata a botšepehi ba pontšo ho matshwao a puisano.Kahoo cheka kholomo redundant (STUB indastering) ho tloha lehlakoreng le ka morao (boroba bobeli).Kahoo bitsoa morao cheka, empa ka kakaretso se ke ua phunya e le hloekileng, hobane tshebetso latelang tla electrolysis theoha koporo e nyenyane, le ntlha ea phunya. ka boeona e supa.Ka hona, moetsi oa PCB o tla siea ntlha e nyenyane.

1) fana ka PCB e nang le lesoba la lisebelisoa. Sebelisa lesoba la lisebelisoa ho beha PCB le ho phunya lesoba;
2) electroplating ea PCB ka mor'a ho phunya lesoba, 'me u tiise lesoba ka filimi e omileng pele ho electroplating;
3) etsa Grafiken lera ka ntle ho electroplated PCB;
4) tsamaisa mohlala oa electroplating ho PCB ka mor'a ho etsa mokhoa oa ka ntle, 'me u tsamaise ho tiisa filimi e omileng ea lesoba la boemo pele ho electroplating ea mohlala;
5) sebelisa lesoba la boemo le sebelisoang ke boro e le 'ngoe ho beha mokokotlo o ka morao, 'me u sebelise mochini oa ho phunya ho phunya lesoba la electroplating le hlokang ho phunngoa morao;
6) hlatsoa morao ho cheka ka mor'a ho cheka mokokotlo ho tlosa li-cuttings tse setseng ka morao.
6. Litšobotsi tsa tekheniki tsa poleiti ea ho cheka ka morao
1) Boto e thata (boholo)
2) Hangata ke 8 - 50 layers
3) Botenya ba boto: ho feta 2.5mm
4) Botenya ba bophara bo batla bo le boholo
5) Boholo ba boto bo batla bo le boholo
6) Bonyane bophara ba lesoba la ho cheka pele ke> = 0.3mm
